Product Description

TCI Tricone Rock Drill Bits:

The TCI Tricone bits drilling for medium to hard rock formation.

The mediium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability. 

The hard formation TCI tricone bits can be used to drill hard and abrasive formation. Wear resistance tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical shaped inserts are used in all rows to provide cutter durability and long life. 

Milled tooth Tricone Rock Drill Bits:

The milled tooth (steel tooth) tricone bits drilling for soft to medium rock formation. 

The soft formation milled tooth tricone bits are used to drill low compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.

The medium formation milled tooth tricone bits are used to drill high compressive strength, medium rock formation. Shoot projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.
